Zack didn't like being left behind. His power was something they could have used. But he understood that he was also the only one would could build the gun and bullet they needed. Technology of all kinds answered to his power. He was alittle nervous since he had never never built a weapon before. It made him think of all the evil ways his power could be used. 

He had grown up with a mother that had raised him to be a hero. In another life or different circumstances he could have turned out like Crusher. Alot of people who grow up the way he had didn't always turn out to be good guys. He pushed the negative thoughts away. They wouldn't do him any good. He focused his attention on the task at hand. He need to make sure that the weapon he was building would do it's job. The other's lives might depend on it.
